TECHNICAL FIELD

The invention relates to the consistent brewing of sweetened beverages and particularly to the provision of a beverage material and sweetener blended product for brewing.

BACKGROUND OF THE INVENTION

When brewing sweetened beverages, such as sweet tea, in restaurants and in the home, there is a lack of consistency from one batch of beverages to the next. For example in tea brewing, the industry uses standard sugar to sweeten tea, and the industry standard is basically one pound of sugar per gallon of tea, which gives a brix of about 11. Brix is a measure (degree) of the sugar content of an aqueous solution. One degree Brix is one gram of sucrose in 100 grams of solution and represents the strength of the solution as a percentage by weight (% w/w). If the solution contains dissolved solids other than pure sucrose, then the Brix only approximates the dissolved solid content. The Brix is traditionally used in tea, wine, sugar, fruit juice, and honey industries to measure sweetness. Brewed sweetened tea has a typical Brix level of 10 to 11. The problem is one usually does not have a scale to weigh out one pound of sugar per gallon of tea so the Brix level varies from one pot or urn of tea to the next. Similarly, this lack of consistency can be a problem when preparing other sweetened beverages as well.

Also in particular to brewing tea, a commercial tea brewing urn typically holds at least 3 gallons of tea and has a brewing basket. A paper filter is placed in the basket and then filled with the tea. Hot water flows into the brewing basket to steep the tea in the basket, and concentrated tea solution is passed into the urn. At the same time, cold water is being delivered into the urn, and the concentrated tea solution and cold water are mixed to make tea. However, when the sugar is added, the temperature of the tea is much cooler so that the sugar is not totally dissolved. Domestic tea machines used in the home, and some restaurants, typically are like drip coffee machines. In domestic brewing the same products and techniques are used, that is, tea is brewed to produce a tea concentrate, then water is added to dilute the tea concentrate, and then the tea solution is sweetened with sugar. For example, there are two typical methods for brewing tea domestically, and each method is made with one teabag to make one quart of brewed tea solution. In the first method, 2 cups of water is brought to a boil on the stove. The boiling water is poured into a tea pitcher on top of one teabag and allowed to steep for 3 to 5 minutes. After steeping, the teabag is removed from the tea solution, and sufficient sugar is added to sweeten the tea to a desired taste profile, that is, a quarter pound or less, and in some instances more. Once sweetened, two additional cups of water are added to the tea pitcher to dilute the sweet tea concentrate. In a second method, a quarter ounce teabag is placed in the brew basket of a domestic coffee maker. Then, 2 cups of water are poured into the coffee maker. The coffee maker will dispense hot water over the teabag to brew a tea concentrate delivered into the coffee pot. The tea concentrate is then poured into a tea pitcher and sweetened to a desired level. Once sweetened, 2 cups of water are poured into the pitcher to dilute the sweet tea concentrate. The preparation of coffee occurs by a similar method, although the addition of sugar and other flavor additives occurs on an individual basis. However, these methods do not provide an effective way to brew sweetened beverages, like coffee or tea, in a consistent and accurate manner.

The commercial tea brewer most commonly used today was invented nearly 40 years ago and has remained relatively unchanged since then. Likewise, the drip brewing method commonly utilized in coffee preparation was invented more than 60 years ago. Therefore, it would be desirable to provide an improved method and apparatus for brewing sweetened beverages, particularly tea and coffee.

Various attempts have been made to improve the brewing of sweetened beverages. US Published Application No. 2010/0159076 A1 shows a floatable infusion package that may include tea and sugar in separate compartments. US Published Application No. 2008/0171110 A1 shows a foraminous plastic vertical tube that can contain tea and sugar, or other solids, which is rigid enough to grip and stir in a liquid to dissolve or infuse its contents. U.S. Pat. No. 2,362,459 discloses an infusion package and the manufacture thereof that includes compartments A and B wherein one compartment contains tea and the other compartment contains sugar. US Published Application No. 2005/0247207 A1 shows a drink infusion device, including tea, having a submersible element and a buoyant retrievable element. U.S. Pat. No. 3,809,215 shows a floating infusion package for tea. U.S. Pat. No. 2,791,505 shows an infusion package having one compartment filled with tea and another compartment filled with sugar. Other patents show various other means of packaging tea and/or sugar. U.S. Pat. No. 2,791,324 discloses a compartmented package that may include tea in one compartment, sugar in another, and creamer in another compartment, which may be poured into a cup of hot water. U.S. Pat. No. 3,186,850 discloses an infusion package containing beverage ingredients, such as powdered tea and sugar carried by a cup, wherein the ingredients are poured into the cup containing hot water. U.S. Pat. No. 4,853,234 discloses a rigid beverage package that can contain any desired beverage ingredients. Each of the references mentioned above are hereby incorporated herein, in their entirety, by reference. None of the prior efforts have provided a way to make sweetened tea accurately and consistently. Additionally, none of the prior efforts have provided a way to make other sweetened beverages accurately and consistently.

Accordingly, an object of the invention is to provide an accurate and consistent way of brewing sweetened beverages, including tea and coffee.

Another object of the invention is to provide a beverage brewing product for use in a drip tea/coffee machine which provides an accurate and consistent way of brewing sweetened beverages.

Another object of the present invention is to provide sources of beverage materials and granulated sweetener particles which can be brewed together in prescribed blend ratios in a brewing basket to form a concentrated sweetened beverage solution that exits the brewing basket with sugar dissolved.

Another object of the invention is to provide a filtering means containing beverage materials and sweetener in a prescribed blended ratio for use in the brewing basket of a drip coffee machine to brew beverages accurately and consistently.

Another object of the present invention is to provide a sweetened beverage product whereby one may pull a brew basket out of the tea/coffee maker and place a mesh thermoplastic pouch containing a prescribed blend ratio of beverage materials and sweetener, and push a start button to brew sweetened beverages consistently, time and time again.

SUMMARY OF THE INVENTION

The above objectives are accomplished according to the present invention by providing a brewing system for brewing beverages comprising a brewing machine having a brewing basket and a brewing pot or urn. A known source of beverage materials and granulated sweetener is provided for placement into the brewing basket during brewing. At least one water permeable sieve, or filtering device, contains the source of beverage materials and granulated sweetener having a sieve size for retaining the beverage materials and granulated sweetener. The beverage materials may include tea, coffee, or a flavored concentrate. A flavored concentrate is a compound of one or more flavoring agents. Flavored concentrate may be granular, powdered, or a liquid that is sprayed onto the sieve, another beverage material, or sweetener and dried to coat such. Also, flavored concentrate may be natural or artificial. Further, examples of concentrate flavors may include, but are not limited to, lemonade, limeade, pink lemonade, peach, mango, raspberry, lemon, or fruit punch.

The granulated sweetener may include, traditional sugar or that produced from agave, coconut sugar, honey, maple syrup, molasses, stevia, or sugar alcohols. The sieve may be a mesh pouch, an open filter, or any other suitable filtering device. The machine includes a hot water dispenser for dispensing hot water into the brewing basket to steep the beverage materials and granulated sweetener in hot water in the basket, dissolving the sweetener, and extracting the beverage flavoring in the water permeable sieve to produce a sweetened concentrated beverage solution. The concentrated beverage solution is diluted by being added to water or other desired liquid. In this manner, the beverage is already effectively sweetened before it is diluted. The diluting liquid may be in the same container the concentrated beverage solution is delivered to, or a separate container to be combined with the concentrated beverage solution.

Tea

In a preferred embodiment, the beverage material includes tea and the sweetener includes sugar which are both contained in the sieve within the brew basket during steeping to produce a concentrated tea solution and, ultimately, sweetened tea, once the solution is added to water. Preferably, the blend ratio of tea to sugar is in the range of 1:3 to 1:35, even more preferably in the range of 1:5 to 1:25, and the sources of tea particles and granulated sugar particles are retained in one of a thermoplastic or cotton mesh pouch and blended together in a prescribed blend ratio. The pouch may be a single pouch or include a first compartment for the tea particles and a second compartment for the granulated sugar. The first and second compartments may be joined together at a fold line so one of the compartments folds over the other compartment in the brewing basket. Alternatively, the tea and sugar may be contained in two separate pouches whereby one pouch sits atop the other pouch in the brewing basket.

In another embodiment, it is contemplated that a mesh or paper filter having an open top and fitting inside the brewing basket may be used. In this particular embodiment, the filter would resemble that of a traditional coffee filter whereby the tea and sugar mixture would be poured into the filter for an open brewing process. Additionally, it is contemplated that the open filter may be used in conjunction with a mesh pouch, each containing one or more of the tea particles and granulated sugar and where the pouch may sit atop or underneath the open filter in the brewing basket.

Preferably, the size of the granulated sugar particles used is in the range of U.S. mesh sieve nos. 3-35; although, particles the size of U.S. mesh sieve nos. 3 or larger will work successfully in the present invention. Granulated sugar particles may comprise a single granule of sugar or multiple agglomerated granules, such as in a sugar cube or sugar pellets. Alternatively, sugar blends consisting of sugar blended with high intensity sweeteners, or any other suitable granulated sweetener may be used. It is also contemplated that other beverage materials, particularly flavored concentrates, may be added to the pouches or tea and sweetener mixture. These concentrate flavors may include popular tea flavors such as peach, mango, raspberry, lemon, lemonade, or any other desired flavor. A method of formulating sugar particles in the above-referenced size range is also described and disclosed herein. The sugar particles produced by the described method may be used for tea, lemonade, coffee, flavored concentrate, or any other beverage that is sweetened.

A method of brewing sweetened tea comprises providing a tea brewing machine having a pot or urn, a brewing basket carried above the pot, and a hot water dispenser for delivering hot water into the brewing basket. At least one mesh pouch or filter containing a prescribed blend of tea particles and sugar is placed into the brewing basket. Hot water is dispensed into the brewing basket for steeping the tea particles and granulated sugar to produce a flow of hot concentrated sweet tea solution from the brewing basket. In the hot concentrated sweet tea solution, the sugar is generally totally dissolved in the solution with the tea. The hot concentrated sweet tea solution is diluted with water which may be in the same or a separate container.

Coffee

In an alternative embodiment, this same brewing product and method may be used to brew coffee, i.e. where the beverage material includes coffee. In a particular embodiment, at least one water permeable sieve or filtering device contains the source of coffee grounds and granulated sugar having a sieve size for retaining the grounds and granulated sugar. The sieve may be a mesh pouch, an open filter, or any other suitable filtering device. Additionally, it is contemplated that the sieve may be an open filter used in conjunction with a mesh pouch, each containing one or more of the coffee grounds and granulated sugar and where the pouch may sit atop or underneath the open filter in the brewing basket.

The same machine as described above may be used, whereby hot water is dispensed into the brewing basket to steep the coffee grounds and granulated sugar in hot water in the basket and extract coffee and dissolve sugar in the water permeable sieve to produce a hot sweetened coffee solution. The coffee solution may be brewed to any desired concentration and may be served hot, diluted with cream, milk, water and the like, and/or may be served over ice to make iced coffee. Typically, iced coffee is brewed as a more concentrated solution whereby the gradual melting of the ice dilutes the coffee.

The pouch may be a single pouch or include a first compartment for the coffee grounds and a second compartment for the granulated sugar. The first and second compartments may be joined together at a fold line so the coffee compartment folds over the sugar compartment in the brewing basket or is folded in the reverse. Alternatively, the coffee and sugar may be contained in two separate pouches whereby the coffee pouch sits atop or is disposed below the sugar pouch in the brewing basket. In another embodiment, it is contemplated that a mesh or paper filter having an open top and fitting inside the brewing basket may be used. In this particular embodiment, the filter would resemble that of a traditional coffee filter whereby the coffee and sugar mixture would be poured into the filter for an open brewing process.

Alternatively, sugar blends consisting of sugar blended with high intensity sweeteners, or any other suitable granulated sweetener may be used. It is also contemplated that other beverage materials, particularly flavored concentrates, may be added to the pouches or the coffee and sweetener mixture. These concentrate flavors may include popular coffee flavors such as vanilla, hazelnut, caramel, amaretto, cream, chocolate, milk, or any other desired flavor.

Flavored Concentrate

In an additional embodiment, this same brewing product and method may be used to brew other beverages, i.e. where the beverage material includes one or more flavored concentrates. A flavored concentrate is a compound of one or more flavoring agents. Flavored concentrate may be granular, powdered, or a liquid that is sprayed onto the sieve, another beverage material, or sweetener and dried to coat such. Also, flavored concentrate may be natural or artificial. Examples of concentrate flavors, and thereby beverage flavors, may include, but are not limited to, lemonade, limeade, pink lemonade, peach, mango, raspberry, lemon, or fruit punch.

In a particular embodiment, at least one water permeable sieve or filtering device contains the source of flavored concentrates and granulated sugar having a sieve size for retaining the concentrates and granulated sugar. Again, the sieve may be a mesh pouch, an open filter, or any other suitable filtering device. Additionally, it is contemplated that the sieve may be an open filter used in conjunction with a mesh pouch, each containing one or more of the concentrates and granulated sugar and where the pouch may sit atop or underneath the open filter in the brewing basket.

Also, the same machine as described above may be used in the particular embodiment, whereby hot water is dispensed into the brewing basket to steep the flavored concentrates and granulated sugar in hot water in the basket and extract flavoring and dissolve sugar in the water permeable sieve to produce a hot sweetened flavored beverage solution. The beverage solution may be brewed to any desired concentration and may be served hot, dilute with water and the like, and/or may be served over ice to make an iced beverage.

Preferably, the blend ratio of flavored concentrate to sugar is in the range of 1:3 to 1:80, and the sources of beverage material and sugar granules are retained in one of a thermoplastic or cotton mesh pouch and blended together in a prescribed blend ratio. The pouch may be a single pouch or include a first compartment for the flavored concentrate and a second compartment for the granulated sugar. The first and second compartments may be joined together at a fold line so the concentrate compartment folds over the sugar compartment in the brewing basket or is folded in the reverse. Alternatively, the concentrate and sugar may be contained in two separate pouches whereby the concentrate pouch sits atop or is disposed below the sugar pouch in the brewing basket. In another embodiment, it is contemplated that a mesh or paper filter having an open top and fitting inside the brewing basket may be used. In this particular embodiment, the filter would resemble that of a traditional coffee filter whereby the concentrate and sugar mixture would be poured into the filter for an open brewing process.

Preferably, the size of the particles of granulated sugar is in the range of U.S. mesh sieve nos. 3-35; although, particles the size of U.S. mesh sieve nos. 3 or larger will work successfully in the present invention. Granulated sugar particles may comprise a single granule of sugar or multiple agglomerated granules. Alternatively, sugar blends consisting of sugar blended with high intensity sweeteners, or any other suitable granulated sweetener may be used. It is also contemplated that other beverage materials, particularly tea particles, may be added to the pouches or the concentrate and sweetener mixture.

DESCRIPTION OF A PREFERRED EMBODIMENT

Referring now to the drawings, the invention will be described in more detail.

As can best be seen in FIG. 1, a brewing machine 10 is illustrated having a container 12, such as a pot, urn, etc., with a lid 14. A brewing basket 16 includes a bottom outlet 18 through which a hot, sweetened beverage solution 26 flows during brewing. That beverage solution 26 may be concentrated or non-concentrated. A concentrated beverage solution 26 is one that requires dilution with a diluting liquid, such as water, as in FIG. 1C. The diluting liquid may be initially frozen, such as ice, and melt to liquid form. Brewing basket 16 is carried in a basket holder 20, in a conventional manner and a lid 22 covers the basket holder. The brewing basket 16 may be removable or integrally formed with the basket holder 20. Additionally, the basket holder 20 may also be removable or integrally formed with the brewing machine 10. Above the brewing basket is a hot water dispenser 28 for delivering hot water into the basket. Lid 14 includes an inlet opening 24 through which the concentrated beverage solution enters into the container 12. A main aspect of the invention is a beverage brewing product, designated generally as A, which is placed in the brewing basket 16 before brewing. The brewing basket 16 may be a circular cup basket, square, or a funnel basket and may comprise more than one piece designed to contain one or more portions of the beverage brewing product A. Further, the brewing basket 16 may be open or closed. In an additional embodiment, the beverage brewing product A, may be sealed into the brewing basket 16 before brewing. It should be understood that while the preferred method of brewing sweet tea beverages, or dissolving concentrated powders to produce sweetened beverages, includes using hot water, these processes may also use water of any temperature, including cold, ambient, or lukewarm water.

As can best be seen in FIGS. 2 and 3, a beverage brewing product A is illustrated which contains a prescribed blend 31 of beverage material 32 and granulated sweetener particles 34 blended according to the present invention. Product A includes a pouch 30 in which a blend of beverage material 32 and granulated sweetener particles 34 are contained. The beverage material 32 preferably includes tea particles. However, the beverage material 32 may also include coffee grounds or a flavored concentrate. A flavored concentrate is a compound of one or more flavoring agents. Flavored concentrate may be granular, powdered, or a liquid that is sprayed and dried onto the beverage brewing product A, the granulated sweetener 34, or another beverage material 32. A flavored concentrate may also be natural or artificial. Further, examples of concentrate flavors may include, but are not limited to, lemonade, pink lemonade, limeade, cherryade, orangeade, peach, mango, raspberry, cranberry, blackberry, fruit punch, vanilla, hazelnut, caramel, amaretto, cream, cinnamon, chocolate, milk, or any other desired flavor or combination thereof. Additionally, the beverage material 32 may also include a mix of coffee or tea and a flavored concentrate, where the concentrate flavor is selected to accentuate the coffee or tea as desired. The granulated sweetener 34 may include granules of, sugar, agave, coconut sugar, honey, maple syrup, molasses, stevia, sugar alcohols, or other like element. Particles of granulated sweetener may comprise a single sugar granule or multiple agglomerated granules.

Pouch 30 is preferably made from a mesh polymer material having a predetermined mesh size to retain the blend while allowing the flavoring from the beverage material to be extracted and the granulated sweetener particles to dissolve in the brewing basket. However, pouch 30 may also be made of any food grade sieve material, including cotton, cellulose, or even metal. It is important to note that in previous brewing methods, such as brewing tea, sugar is added to the beverage solution after it is brewed and has been cooled. Thus, the sweetener utilized to sweeten the beverage is thus dissolved in a cool beverage solution, reducing its ability to be dissolved.

FIG. 2 shows mesh pouch 30 cut away to show the beverage material and sweetener blend 31 (beverage material 32 and granulated sweetener particles 34) contained in the pouch. FIG. 3 shows the beverage brewing pouch A placed in brewing basket 16 of the brewing machine. As the hot water fills the filter basket, pouch 30 generally becomes submerged in hot water 29 as in FIG. 1B. The steeping of the beverage material 32 and granulated sweetener 34 extracts the flavor from the beverage material 32 and dissolves the particles of sweetener 34 producing a sweetened beverage solution 26 dispensed through the basket outlet 18 into container 12 through container lid opening 24. Because the sweetener 34, such as sugar, is steeped in hot water, more of the sweetener 34 is dissolved quickly than when sweetener is added to the beverage solution after brewing in the urn. Beverage brewing product A may also be steeped in 2 cups of water in a container to make a concentrated or non-concentrated beverage solution. If concentrated, a proportioned amount of diluting liquid, such as two cups of water or equivalent amount of ice, are added to the solution to create the beverage solution. Either way, the Brix of the solution is consistent since the same blend of beverage materials and granulated sweetener is known.

Pouch 30 is preferably constructed from any suitable FDA approved polymeric material such as nylon, polyester, polypropylene, polyethylene, or cellulose in a woven or nonwoven material, and preferably is 4″×4″ to 6″×6″ in size. However, pouch 30 may also be made of any food grade sieve material, even including metal. In some applications, it may also be possible to utilize a cotton nonwoven or woven fabric. The term mesh is meant to include a fabric or material having defined regular openings such as in a woven material, screen, etc., or random openings such as found in a non-woven material like a thin web of fibrous materials, scrim, etc. which may provide the same permeability. For example, a non-woven fibrous web with a polyester/polypropylene blend may be used.

With regard to sugar as a granulated sweetener, sugar refiners run sugar through a series of sieves rated with a US mesh number. The granules of a certain size get caught or retained in the sieve with smaller holes than the size of the granule. This is done in order to provide uniform size granules to the market. Typically, the sugar found in grocery stores and restaurants are of a small granule particle size and are retained in a mesh sieve the size of 45-120. The smaller the mesh number, the larger the granules of sugar are, and the larger the mesh number, the smaller the granules of sugar are. For example, a sugar granule of mesh sieve size 3 would be larger in size than a sugar granule of mesh sieve size 35. This sizing standard is relevant to all sweeteners. It has been found, according to the present invention, that an advantageous size of particles of sweetener, particularly sugar, is that retained by US sieve numbers 3-35, although granule sizes larger than 3 will work as well. Therefore, a typical sweetener, like sugar granules, found in stores and restaurants, at a mesh sieve size of 45-120, is smaller than the size preferable for use in the present invention.

Referring now to FIG. 4, an alternate embodiment of the invention is illustrated for a beverage brewing product B wherein the beverage material 32 and granulated sweetener particles 34, are contained in separate compartments 36 and 38 of pouch 30′. Each compartment is formed from a mesh material as disclosed for product A, shown in FIGS. 1 through 3. In addition, the two compartment pouch includes a seal 40 around the pouch and a seal 41 dividing the pouch into compartments 36 and 38 and providing a fold line. Thereby, as shown in FIGS. 5 and 6, one compartment of the product B may be folded over onto the other compartment during brewing in a brewing basket 16.

FIG. 7 illustrates another embodiment of the invention C wherein the beverage material 32 is contained in one pouch 42 having a seam 44 around its edges, and the granulated sweetener particles 34 are contained in a separate pouch 46 also having a seam 48 around its edges. Compartments 42 and 46 are scaled in any suitable way, including the four-sided seal of FIG. 4. In 30″, one compartment may be placed on top of the other during brewing in much the same manner as with the folded tea sweetening brewing product B, as shown in FIGS. 5 and 6. In addition, the brewing basket 16 may be constructed so that each of the pouches 42, 46 are contained in a separate space therein and water passes through each in serial order. For example, the brewing basket 16 may have a first piece through which water may pass that contains one pouch and which is stackable upon a second piece through which water may pass that contains the other separate pouch.

Referring now to FIGS. 8-10, an alternate embodiment of the invention is illustrated for a beverage brewing product D wherein the sieve is an open filter 50 having a seam 52. Alternatively, the open filter 50 may also be formed without a seam. The filter 50 in FIGS. 8-10 is a funnel shape, however it may be any shape. For instance filter 50 may be a cup or bowl shape. The filter 50 is formed from a mesh material disclosed for product A. The blend 31 of beverage material 32 and granulated sweetener particles 34 is added to the filter. As seen in FIG. 10, the filter 50 containing the blend 31 of product D may be placed within a brewing basket 16 to be utilized for an open filter brewing process.

Referring now to FIG. 11, an alternate embodiment of the invention is illustrated for a beverage brewing product E wherein the sieve comprises an open filter 54 containing the beverage material 32 and a pouch 58 containing the granulated sweetener separately. The filter 54, similar to that of product D, also has one seam 56, although it may have no seams or more than one. Alternatively, the filter 54 may contain the granulated sweetener particles 34, while the pouch 58 contains the beverage material 32, as in FIG. 12. The pouch 58 may be disposed either on top of the filter 54 in the brewing basket 16, as in FIG. 11, or underneath the filter 54, as in FIG. 12. The filter 54 and pouch 58 of product E is formed from a mesh material disclosed for product A.

In regard to the present embodiments, product A, B, C, D, and E, the product A embodiment is advantageous because larger particles of sweetener, such as sugar, are mixed in with the smaller particles of beverage materials, such as tea, making the sweetener dissolve faster and more fully. In addition, the beverage flavor is extracted more fully in the blend because the granules reduce the compacting of the beverage materials. Larger granule sweetener particles allow hot water to flow around and contact the particles at the same time as the flavor is being extracted out of the beverage materials. Thereby, two steps have been reduced to one. In the prior method, the sugar goes in after the tea has cooled in a two-step process.

In accordance with the invention, a method for brewing a sweetened beverage is disclosed comprising the steps of providing a brewing machine having a container, a brewing basket carried above the container, and a hot water dispenser for delivering hot water into the brewing basket. Next, the method includes placing a mesh pouch or open filter containing a prescribed blend of beverage material and granulated sweetener particles into the brewing basket, and dispensing hot water into the brewing basket to steep the beverage material and granulated sweetener particles in the brewing basket producing a flow of sweetened beverage solution out of the basket into the container. If concentrated, the concentrated beverage solution is added to a proportioned amount of diluting liquid, like water, at a time after the sweetener has been more completely and consistently dissolved in contrast to the sweetener being dissolved in the beverage solution after brewing. When performing an open brew process, it is preferable to store a loose tea and sugar mixture in storage bags or pouches constructed from metallized polypropylene or metallized polyethylene, whereby the loose tea and sugar mixture may be poured from the metallized bag into an open filter.

Referring now to FIGS. 13A, 13B and 14, a system and method for producing the beverage brewing product A in pouch 30 will now be disclosed in more detail, along with the process for blending the beverage material and sweetener, and packaging. As can best be seen in FIG. 13A, a blending apparatus, generally designated F, for feeding and blending beverage material 32 and sweetener 34 is illustrated. Apparatus F includes a feeding section G having a separate beverage material bin 66, and a separate sweetener bin 64 which separately deliver beverage material 32 and granulated sweetener 34 through conduits 68 and 70 through separate infeed ducts 72, 74, respectively. From the infeed ducts, beverage material 32 is delivered to a hopper 76 and sweetener 34 is delivered to a separate hopper 78 of blending section H. A feed auger 80 is located in hopper 76, and a feed auger 82 is located in hopper 78. The augers meter or control the amounts of the beverage material and granulated sweetener being delivered by controlling the auger speeds, and hence the blend ratio. The preferred beverage material/sweetener blend depends upon the chosen beverage material and sweetener. For flavored concentrate and sugar, the ratio is within about 1:3 to 1:80. For tea particles and sugar, the ratio is within about 1:3 to 1:35, and preferably within 1:5 to 1:25, depending on the customer, with 1:12 being typical. Additionally, the size of the tea particles varies with the customer's tea blend. Tea is widely available, for example, Henry P. Thomson Tea Company in Peapack, N.J., is a source and the specifications are for black, oolong, and green (including white tea). Generally, for most tea blends, 98% of the tea particles will be retained by a U.S. mesh sieve size of 80.

The portions of beverage material 32 and granulated sweetener 34 are fed into a blending and dispensing funnel 84 where the beverage materials and granulated sweetener are blended and dispensed through a nozzle 86. As can best be seen in FIG. 13B, the blending and dispensing funnel 84 may include any arrangement or device for spreading and blending the beverage material and granulated sweetener. In the illustrated embodiment, funnel 84 includes a plurality of layers of wire grates 86 and 88 angularly oriented at angles with each other to provide irregular grate openings 90 for the blend delivered through the funnel. Funnel 84 includes a bottom opening through which the blend 31 is delivered to a conduit or nozzle 92. Packaging section I includes a tubular roll of mesh material 94 being fed downwardly, which may be either tubular or flat mesh material delivering from roll 96 to be seamed tubular. As the stock mesh material is drawn downwardly over nozzle 92, by roller conveyors 93, a side heating bar 106 seals the edges of the mesh material together. As in a typical vertical form, fill and seal machine, a pair of moveable heating and cutting units 102, 104 are provided. Each unit includes heated sealing bars 118 above and below the respective knife blade 112 and knife slot 116. Sealing and cutting unit 104 includes knife blade 112, and sealing and cutting unit 102 includes knife slot 116 which receives the knife blade when the heat bars of the units are pressed together for sealing and the seam is then cut. Knife 112 extends into knife slot 116 of unit 104 to cut midway through the seam forming a top seam 100 for the pouch below and a bottom seam 98 for the pouch above.

As can best be seen in FIG. 14, tubular mesh material is initially sealed across the lower bottom end at 98 by the previous seal and cut operation, leaving the mouth open whereupon the blend 31 goes down through nozzle 92 into pouch 30. The pouch is dropped into a bin 99 and conveyed away. The next material is delivered to the sealing/cutting station 120 and its lower end sealed at 98 by the previous seal and cut operation and with its mouth open. The next pouch at sealing/cutting station 120 is then filled and sealed across the top whereupon the next bottom seal 98 is formed at the same time. Horizontal form, fill, and seal machines can equally be used to produce product A, B, C, D, and E.

Thus, it can be seen that an advantageous product and process can be had according to the present invention for brewing a beverage and dissolving a sweetener together in a brewing basket. A sweetened beverage solution flows out of the brewing basket into the urn which, if concentrated is mixed with a diluting liquid, like water, for consistently brewing a beverage. Preferably, at least one pouch, in the form of a fine polymeric mesh pouch, retains the beverage material and sweetener during brewing. The sweetener dissolves rapidly and more fully in the present invention when the granular size of the sweetener is generally U.S. Mesh sieve 35 or larger (i.e. lower mesh numbers) as opposed to when the granular size of the sweetener is generally smaller than U.S. Mesh sieve 35 (i.e. mesh sieve numbers above 35). The beverage material and the sweetener blended in the mesh pouch brew and sweeten the tea at the same time. The hot water entering the brew basket brews the beverage, dissolves the sweetener, and sweetens the beverage. The temperature of the water is one of the key factors in brewing. Utilizing hot water in the brewing basket helps dissolve more of the sweetener quickly. Larger granulated sweetener allows the water to flow around and make contact with the sweetener at the same time it is extracting flavor from the beverage material in the blend. The steps of brewing a beverage in a pot or urn, and then adding sugar to the beverage is replaced by one step, brewing the beverage and sweetening at the same time before they reach the urn.

In one embodiment of the present invention, it is contemplated that granulated sugar in the range of U.S. mesh sieve nos. 3 to 35 may be manufactured, as it is currently difficult to find sugar in this size range that is commercially available in the United States in large quantities. One preferred method for manufacturing sugar granules (or agglomerations) in this size range includes forming sugar pellets from sugar that is commercially available in smaller sizes, and then breaking the pellets up into smaller sugar granules or chunks.

Commercial pellet mills are commonly used to form pellets from materials made from smaller granules, including feed mill pellets, wood pellets, and the like. These pellet mills may also be used to manufacture sugar pellets from sugar that is already processed into smaller granules. For instance, California Pellet Mill manufactures and sells a number of different commercial pellet mills that may be used in the instant process. In such a process, small granulated sugar is fed into the pellet mill, and formed into larger pellets. These pellets may be used in the beverage producing processes described herein, either as produced in pellet form, or the pellets may be broken up into smaller chunks (but still larger chunks than the original granulated sugar that is fed into the mill), in order to generate sugar granules or chunks that fall within the desired sugar size range as described herein.

The pellets may then be fed into a lump breaking machine (or lump breaker) to reduce the size of the pellets, as desired. Lump breaker machines are commercially available, such as the Model RDC 1515-SS from Munson Machinery, and are commonly used for the deagglomeration of free or non-free flowing bulk materials such as salt, sugar, spices and resins. After the sugar pellets have been fed through the lump breaker, the resulting sugar granules may then be used to sweeten various beverages in the processes described herein.

Additionally, a powdered beverage concentrate, such as lemonade or any other flavored concentrate, may be mixed with sugar, and the concentrate/sugar mix may be fed into a pellet mill to form pellets, which are then placed into a sieve, pouch, or any suitable container. Then, the pellets may be dissolved in water in any of the processes described herein, thereby forming a flavored beverage.
